Apparatus for setting function of switches of construction vehicle

Abstract

The present invention relates to an apparatus for setting a function of switches of a construction vehicle, enabling a construction vehicle driver to freely set or arrange the switches as desired, so that the driver feels more convenient to use the switches and thus, the work efficiency can be improved. Preferably, the apparatus includes a plurality of switches for generating an on / off signal; a controller for receiving a signal from the switches and outputting a driving signal to drive the work equipments; a plurality of driving units for driving the work equipments; a memory for storing relations between the switches and the driving units driven by the switches; and a pattern editing unit which includes a display screen and a plurality of input buttons, whereby a construction vehicle driver can change the relations between the switches and the driving units, the relations being stored in the memory.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates in general to switches of a construction vehicle, and more particularly, to an apparatus for setting a function of switches of a construction vehicle, whereby function of each switch required for driving work equipment of a construction vehicle can be freely set. [0003] 2. Description of the Related Art [0004] In general, a construction vehicle like an excavator is provided with basic work equipments such as a boom, arm, bucket, and swing motor, and also additional work equipments such as a rotator, hammer, and power boost. The boom or the arm is driven when hydraulic fluid is supplied to a hydraulic cylinder with the spool of a control valve moving according to control signal from an operation lever. On the other hand, the rotator starts or stops when a switch generates an on or off signal. [0005] In effect, there is a plurality of switches for driving the additional work equipment. Th...

Benefits of technology

[0009] It is, therefore, an object of the present invention to provide an apparatus for setting a function of switches of a construction vehicle, enabling a construction vehicle driver to freely set or arrange the switches as desired, so that the driver feels more convenient to use the switches and thus, the work efficiency can be improved.

Problems solved by technology

Unfortunately however, the arrangement of the switches varies according to manufacturers.

For instance, if a driver is familiar with the arrangement (or setting) of switches for one construction vehicle of a particular manufacturer, he would feel inconvenient in driving another construction vehicle of a different manufacturer where the arrangement of switches is totally different from the one he is accustomed to.

Therefore, in some cases, switches that a driver seldom uses could be installed on the handle of the operation lever and the switches that the driver uses frequently are not installed on the handle of the operation lever.

This contradicts the original primary purpose of the switches for maximizing drivers' convenience.
